Start by finding TDC and go up from there and get every thing "spot on" in the center of the specs. and see what happens. I chased my problem for a couple weeks before finding out this. Model A's seem to have a remarkable way of having a fuel problem when it is an ignition problem and the other way around.

Sir you turned my words around, the carburetor is running rich ( period) it's running so rich that it maybe using up the available fuel
When drinking a strawberry shake you get a brain freeze ( to much shake) and then you suck up a piece of strawberry and the flow stops lol
His problem is the carb is way to rich ( sooty plugs #1 plug has liquid leaking around the outside of it) and maybe running the carb dry.
Adjusting the carb idle mixture and idle speed may take care of the rich mixture, and I hope he has a carb inlet filter that could be dirty/ clogged. The only electrical issue could/would be with dirty/fouled spark plugs ...hopefully
His words first gear is alright , second gear is 90%, third gear stumbling or missing until 40-45 mph and then all is ok!
